The speed cook feature of this microwave reduces cooking time by 30%. The sensor cooking feature of the LMVH1750 microwave gauges the humidity of the food cooking and stops automatically when it is finished, thereby eliminating over and under cooking. Convenience features such as Popcorn Key and Custom Cook, present throughout the line, are also present here. Besides its convection technology, the LMVH1750 is a step up from the lower cost LMHM2017ST in that it has a 2-line VFD display (as opposed to a plain VFD display), and halogen cooktop lighting (as opposed to incandescent). The LG LMVH1750 comes with a one year parts and labor warranty.
